Ultrasonic Measurement of Elastic Moduli in Slender Specimens Using Extensional and Torsional Wave Pulses

CODEN: JTEVAB

Abstract

The pulse-echo method using extensional and torsional waves is described relative to determining elastic properties and other characteristics of specimens which are slender acoustically. Several applications are reviewed, including: glass fibers of diameter 16 to 42 μm; glass rods of diameter about 1 mm, tested to 700°C; iron-base alloys of diameter 3.2 mm, tested from nearly −200°C up to +200°C; titanium specimens of rectangular cross section, 1.5 × 3 mm; and tantalum-base alloys of diameter 6.4 mm, tested up to 1400°C. Limitations are pointed out regarding dispersive materials and geometry.
